NASA is preparing to launch the Webb telescope out to space. It will let us know how all started:

Is this connected in any way with the Eyeglass telescope that Robert Lang helped develop at the turn of the century? "Doubled in size, the telescope could no longer fit aboard any existing rocket. That meant the telescope’s mirror would have to be foldable and would have to assemble itself in space. NASA eventually settled on a mirror 6.5 meters wide — almost three times the size of Hubble’s and with seven times the light-gathering power. But all the challenges of developing and building it remained. If the foldable mirror operates as planned, the mission could augur a new way to launch giant telescopes too big to fit on rockets. “ Laura Rozenberg
